Abstract
A double ended inverter system suitable for use with an AC electric traction motor of a vehicle is provided. The double ended inverter system cooperates with a first DC energy source and a second DC energy source, which may have different nominal voltages. The double ended inverter system includes an impedance source inverter subsystem configured to drive the AC electric traction motor using the first energy source, and an inverter subsystem configured to drive the AC electric traction motor using the second energy source. The double ended inverter system also utilizes a controller coupled to the impedance source inverter subsystem and to the inverter subsystem. The controller is configured to control the impedance source inverter subsystem and the inverter subsystem in accordance with a boost operating mode, a traditional inverter operating mode, and a recharge operating mode of the double ended inverter system.
